What is Java Timer Class? How to schedule a task to run after specific interval?

The Timer class is used to perform an action after a time delay. Here is an example:

import java.util.Timer;

import java.util.TimerTask;

public class TimerExample{

    Timer test_timer;

    public TimeDelay(int seconds) {

        test_timer = new Timer();

        test_timer.schedule(new DelayTask(), seconds*1000);

}

    class DelayTask extends TimerTask {

        public void run() {

            System.out.format("Timer has run out.%n");

            test_timer.cancel(); 

        }

    }

    public static void main(String args[]) {

        new TimeDelay(5);

        System.out.format("Task has been scheduled.%n");

    }

}
